Report
I highly recommend McMaster. Being from out of state, we didnt know what company to contact. We needed two complete heating and a/c systems installed. Both Ron and James were most helpful in finding the Carrier products that suited our needs. The McMaster technicians who installed the new system were very professional and polite.

Report
We talked to five different companies regarding replacing our 3-ton 23-year-old Carrier HVAC furnace+AC system. Ron was the most impressive of the bunch, he knows his stuff and he was the only one that sat down with us to lay our our options and to answer all our questions. His estimate wasn't the lowest, but we were confident that we'd be getting a quality system expertly installed. Everyone on his team was professional and helpful during the installation and afterwards, and the new Carrier system is working great.

I had a central air conditioner installed on 8-6-20 by McMaster heating and A/C company. They did an awesome job. All the workers were polite and very efficient. In 2011 they also installed a 4 ton gas furnace in the attic with all the ducts, and I am very pleased. I highly recommend McMaster company with any heating or A/C needs. Guy Morrison

Report
We had a new AC unit installed by McMasters recently. Ron was great to work with, gave us tons of information and options and we couldn't say no. We upgraded to a better AC unit for efficiency and the price was super competitive or better then other companies we called. The install was completed within the time frames including changing all the vents within the house. They complied with all safety measures during this COVID time and we couldn't be happier with McMaster air. We loved them so much, we called them to install a new AC unit in my mom's house. We highly recommend McMaster Air, and will use them for all our HVAC needs.

McMaster's is the best. Honest and fair. This is the second system they have done for me. I used them in my old house and would not have trusted any one else for the job. Outstanding work and great customer service.
